T all whom ib may concern:

it known that l, Jenn CAIN, a iizen of the United States, and a resident oi Chicago, county of Cook, and llinois, have invented certain new l Improvements in Windshie ate of i and useiu Wipers, or" which the following is a specifilie invention relates to wind shield wipers, and has for its pr ncipal ob ect the 2, is a section taken on line 2-2 of 1. r

Fig. 3, is a. section. taken online 8'45 of Fig. 9. p

Fig. l is a sectiontalren on line 4l-t of .1, and showing in dotted lines a changed position of certain of the parts.

Referring to the drawings 10 indicates the glass plate of a wind shield; the upper transverse frame part of by the numeral 11-. rhchannel bar 12 is mounted upon the frame bar 11, having angle bars 13 and 14 adjustably mounted upon the flanges thereof, the adjustability being secured by the use of slotted openings for the screws 15 by which said angle bars are mounted in position. A strip of fiber 16 is mounted upon the inner face of the web portion of the channel ,bar, and fiber strips 17 are mountedupon the inner faces of the bars or plates 13 and 14 such fiber plates being mounted in position to take the wear between the frame bar 11 and the slide-block comprising the channel 12 and the parts connected thereto. The fiber strips 16 and 17 also serve as means for reducing the sound to a minimum as the device is moved along the frame bar 11as hereinafter described.

By making the plates or bars 13 and lt W 1 "'4 L lian/QUE,

comprising means by whicn the 1, is a face view of one end portion.

which is indicated adjustable respect to the channel 12,

the device is capable of being secured easily and quickly in position upon ordinary size or shape 0-: car used connection with wind shields. Q

l he channel 12 in provided w ch vertically disposed sleeves l8 opposite sides thereof, which constitute sockets for the reception. or the upper portions of rods 19 which extend downwardly along e opposite faces of the glass 10. Eileeves 20 are revolubly mounted upon the rods 1%, losing equipped with wipers 21 formed or"- india rubber, or other suitable material, being mounted in position to engage the opposite face of-tne glass 19. s is best shown in 3, the sleeves 20 are notched at their lowerends, pins 22 being mounted in the lower ends of the rods 19 to engage the slots in the sleeves for supporting the wipers and for limiting; the rotary movement of the wipers about the rods.

Means is provided for moving the slide bloclr and the-wipers carried thereby transversely along the wind shield. in the construction shown, this means comprises a handle 23 of any approved type, mounted by means of a' screw threaded pin 2% in a suitable screw threaded opening in the rod 19 upon therear face of the wind shield. its is shown in 3, the opening through the sleeve 20 for the pin 28 is in the term of a slot 25, whereby the sleeve and the wiper are permitted to rock slight y about the rod 19.

When it is desiredto-use the device as? hereinafter claimed, since other materials may be available which will serve the same purpos v As t a device is moved toward the right in Fig. 1, the wipers to thelimit of their motion as shown in solid lines in at, and when the device is moved toward left in Fig.

will be "caused to turn toward the left at v iaoeeai 1, the wipers will'be turned by their frictional engagement with the glass to the limit of their motion toward the right as shown in dotted lines in said Fig. 4%. In this way, the desired squeegee etlectv is obtained, and the wipers are rendered very effective for cleaning purposes.

ll hile l. have illustrated and described the preferred form of construction for carrying my invention into effect, this is capahle of variation and modification without departing from the spirit of the invention. l. therefore, do not wish to be limited to the precise detailsof the construction set forth, but desire to a ail myself of? such variations and modifications as come Within the scope of the appended claims.

Having described my-invention, what ll claim as new and desire to secure by Letters Patent is 1. i-l device of the character described through circumferentially disposed open-.

ings in said sleeves for limiting the rotary movement of the wipers on the rods; and a handle mounted on the device for moving it from side to side upon the wind shield, substantially as described.

2. A device of the character described comprising in combination a short channel bar adapted to be mounted on a transversely extending, frame bar of a wind shield; diagonally disposed plates adjustably mounted on the sides of said channel bar for holding same in position on the frame bar; lining strips carried by said channel bar and said diagonally disposed plates for reducing sound; rods mounted onsaid channel bar and extending along the face of the glass of the wind shield on opposite sides thereof; sleeves revolubly mounted on said rods; wipers mounted on said sleeves; pins carried by said rods extending through circumferentially disposed openings in said sleeves for limiting the rotary movement of the wipers on the. rods; and a handle mounted on the device for moving it from side to side upon the wind shield, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
